        -b           -25         -25         
x = ------  ⇒ --------- = -------- = 2.6 
       2a         2(-4.9)     -9.8

enot [183]

(3t^2 + 2 + (-2)) + (t^2 + 3t - 4) - (4 + (-5))

Apply the distributive property to remove parentheses.

Combine like terms.

<h3>4t^2 + 3t - 3 is the simplified form of the given expression.</h3>

PLZZZ HELP ME I DON'T GET THISq
just olya [345]

Answer:

Step-by-step explanation:

To distribute means to multiply everything outside the parenthesis with everything inside the parenthesis, so in this case 7x8 then 7(x) then 7x2 so that is equal to 56 + 7x + 14, so combine the 56+14 so we get 7x + 70.  I hope '7' is part of the problem and not the question number
